To all e072 0% 2'15 m a-y concern Be it known that I, FELIX Hnrs'rrin, a citi- 'zen of the United States,'resicling in New York in the county of New York and Stateof New York, have invented a new andfuse ful Improvement in Processes and Apps rat-us ior Closing Filled Cans, of which-the following is a specification.

Thisginvention relates in general tofthe The principal object ofithe invention is the provision' of an apparatus which will permit the can end: to be placed-on. the can body and pressed downtightly thereegainst or new You n. ASSIGNOE"TOJAMERIGAJ YORK, N. Y., conronerron newzrnnsnr. v

turedeppa'ratus f rLtl'ie purpose mentioned, 7 the parts of'which will be $05 constructed and arranged as to minimize occasion for repair and replacement and which mum-'1 'du'ce ithe necessity, for: adjustment of the 'parts; of the apparatus: In "connection with the last named object-it is pointed "out; that apparaltu s'of this character isusually used by packers and canners, 'manyfof whom are without expert machinists 7 and j mechanics and without a machine'shop equipment,-and since tl 'e 'product cannedmust be handled Q withentreme ezepediti'on nfter'itis receive anyfloss of-tiine required throughsth iiicepa'citation of the apparetustor any cause is extremely costly; i r i V I 1 f Numerous other objects and advantages v or the invention will be apparent it is' so that the contents maybe compressed or; better understood from the following" debrought to a. sufficiently lowleve to permit accurate seating of the end orcover on the body and which will permit also the cans to beremoved from the end feeding station and'held in this pressed relation until other and further OPQI'QUOH :as for example proc- 1 essing and the like, is accomplished.

. In um feeding ota eardinecun considerable ditficulty and annoyance has-resulted "from the tendency of the'endfto be disllatetl to provide'an inte provisionv of an uppers placed by upward pressure of the contents or through imperfect seating ofthe end in"- its initial'application, and efi'ort has been 'made to overcome this by applying the end in interlocked relationiwith the body e therby eonjointly bending the 'sarrne or providi'ng the end with bent-flanges into which flanges of the can bodynre inserted or threaded. 5 i I Y My invention contemplates a much jsim pler, more effective and positive apparatus and process wherein the end is pressed down directly upon the can body and there maintained by being held in. pressed relation obviating an necessity of threading one V flange of enecpart into flanges of another or performing any mechanical operation calcurlocltinp; relation between the parts, 1 1 J ,Y 1

Another objectdot my invention is the 7 tus having this and other advantages which will insure against therelease or deliveryof any can end when there is no can body there to receive it;

iknother object of the invention is the provision of simply and easily manufac scription when considered "in connection V with the accompanying drawing illustrat 5 ing'e preferredjembodiment thereof. 1

This means consists in the presentinstance of guides 81 (Figs. 3 and 6) having curved or bevel. ends 9 and arranged to extend down from be neath the top plate 23-at the discharge side. These guides may be connected by plate 82 with similar guides 83 extending along above the travel' of the conveyer and the dimensions ot' the parts being-such tha the can, end is held substantially in contact with the top of the body as the can is moved ahead.

The can end is thus pressed down upon the top oi": the body by pressure exerted upon the upper face ot the end and the under face of the body and this pressureis maintainedin like manner so long as 'may be desirable. in passed through an oven or other processing apparatus, or if desired merely through means to secure the end in place.

I It is thought that the invention and'many of its attendant advantages will be under: stoodfrom the foregoing description, and

it will be apparent that various changes may be made in the form, o struction and arrangement of the parts without departing from the-spirit and scope of the invention or sacrificing its material advantages, the form hereinbetore described being merely a preferred embodiment thereof. I
